Cannot turn on Facebook post notifications on iPhone 13.
I cannot turn on notifications on my iPhone 13 when someone comments in a Facebook group. It used to be that I would click on "..." in the upper right corner and I would get an option to "turn on notifications for this post." This still works on my laptop, but that option no longer appears on my phone. I have tried restarting my phone, signing out and back in to Facebook, deleting and reinstalling the Facebook app, and checked my notification settings for Facebook and my phone settings. I've tried all the suggestions I can find online. There are some posts that I really want to follow comments on, but I can't figure out how.
